When do babies move from rolling over to sitting up?

One day your baby is rocking from back to tummy — and a few weeks later they're propped up, taking in the whole room. That bridge from rolling to sitting is one of babyhood's loveliest leaps.

In short

Most babies roll over (both ways) by around 6 months and learn to sit up steadily on their own between 6 and 9 months. Rolling builds the trunk strength and head control that sitting needs, so the two skills naturally flow into each other over a few months. Every baby has their own pace, and a window of a month or two on either side is perfectly normal.

How the skills connect

Rolling and sitting aren't separate boxes to tick — they're stages of the same growing core strength.

• 4–6 months — your baby rolls front-to-back, then back-to-front, and begins pushing up on their forearms during tummy time.
• 6–7 months — they can sit with their hands propped in front (the "tripod" sit) for short bursts.
• 7–8 months — sitting becomes steadier and hands come free to reach for toys.
• 8–9 months — many babies learn to get themselves into sitting from lying down, and start pivoting toward crawling.

Plenty of floor time on the tummy is the single best way to help — it strengthens the neck, back and shoulders that sitting depends on.

When to check in

Milestones are a guide, not a stopwatch. It's worth a friendly developmental check if by around 9 months your baby isn't rolling at all, can't hold their head steady, seems very stiff or very floppy, or always uses just one side of their body. These aren't alarms — they're simply good reasons to have a quick look together.
